Doing work refers to the process of transforming energy from one kind of formality to another. Two factors necessary to do work: the force acting on the body and the distance the body passes in the direction of the force. Classical mechanics Definition: When a force acts on a body and causes the body to pass a distance in the direction of the force, mechanics says that the force does work on the body.

Work done: W=Fd

Force: F=W/s

distance : s=W/F
